Abstract

The utility model discloses a large-diameter valve hydraulic pressure test clamp comprising a value and a clamp. The large-diameter valve hydraulic pressure test clamp is characterized in that the clamp comprises anti-loosening sleeves and clamping rings. A port of the valve is provided with a pressure testing block plate. The external periphery of the port of the valve is provided with grooves. The clamping rings are clamped in the grooves and fixed in a coordination way. The anti-loosening sleeves are sleeved on the external ends of the clamping rings. According to the large-diameter valve hydraulic pressure test clamp obtained from the utility model, processing technology is simplified so that the large-diameter valve hydraulic pressure test clamp is easy to use and operate, and thus labor intensity is reduced and production cost is reduced.

Description

Large bore valves hydraulic testing fixture
Technical field
The utility model relates to a kind of test fixture, particularly large bore valves hydraulic testing fixture.
Background technology
Be directed to the pressure part of this series structure, normal employing has two types at present: special-purpose water pressure testing board, adopt special-purpose water pressure testing board, and not only expensive, and also delivery date is long, is difficult to meet order requirements; Adopt screw thread fixture, adopt screw thread fixture (method that petrochemical complex butt welded pipeline adopts): major thread exists processing difficulties, the drawbacks such as difficulty are installed, bore is larger, difficulty is larger, after pressure testing, will carry out secondary processing, and the turning of screw thread part is fallen, car, to soldering opening size, causes cost significantly to increase again.
Utility model content
The purpose of this utility model is that a kind of simple in structure, large bore valves hydraulic testing fixture of reducing labour intensity is provided in order to solve above-mentioned the deficiencies in the prior art.
To achieve these goals, the large bore valves hydraulic testing fixture that the utility model is designed, comprise valve and fixture, it is characterized in that: this fixture comprises loose-proof sleeve and snap ring, described valve port is provided with pressure testing closure plate, valve port periphery is provided with groove, and snap ring is stuck in groove and is fixed, and described loose-proof sleeve is enclosed within snap ring outer end.
Preferably, between described pressure testing closure plate and valve inwall, be provided with O-ring seal.
The large bore valves hydraulic testing fixture that the utility model obtains, has simplified processing technology, has used minimizing labour intensity simple to operate, reduces production costs.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: valve 1, pressure testing closure plate 2, snap ring 3, loose-proof sleeve 4, groove 11, O-ring seal 21.
Embodiment
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Embodiment:
As shown in Figure 1, the large bore valves hydraulic testing fixture that the present embodiment provides, comprise valve 1 and fixture, this fixture comprises loose-proof sleeve 4 and snap ring 3, described valve 1 port is provided with pressure testing closure plate 2, valve 1 port is arranged with groove 11 outward, and snap ring 3 is stuck in groove 11 and is fixed, and described loose-proof sleeve 4 is enclosed within snap ring 3 outer ends.Between described pressure testing closure plate 2 and valve inwall, be provided with O-ring seal 21.
Above loose-proof sleeve 4, snap ring 3, test closure plate 2, independent processing separately, quality of fit is less demanding, only needs machine tool just can meet processing request, simplifies processing technology.
Assemble very simple: first pack the pressure testing closure plate of wearing O RunddichtringO 21 into valve 1 porch, again snap ring 3 is snapped in, finally loose-proof sleeve 4 is inserted in, because loose-proof sleeve 4 is same conical with snap ring 3, easily pack into, compare with Screw clamp and (need to firmly impact screw thread with hammer, dismounting is wasted time and energy, likely, because threaded engagement is bad, there is the possibility of killing in hydraulic testing rear thread), greatly reduce workman's labour intensity.

Claims (2)
